1: Washi Tape Pattern

If you live in a dorm or apartment, it may be against the rules to permanently affix decor onto the walls. Cue the washi tape. Use a variety of colors and patterns to get a custom look you love, and simply switch it out when you want a new look. Design by Michelle Edgemont

2: Elegant Sconces

Dress up even the smallest of areas, like a nook or entryway, with a little bling. Designer Jamie Herzlinger flanked a French-style settee with ornamental sconces to add some sparkle to the plain wall.

7: Rustic Baskets

To decorate the staircase wall, cousins Anthony Carrino and John Colaneri of Cousins Undercover hung rustic wood-and-wire baskets. Check your local thrift store for vintage finds that are easy to hang and eye-pleasing.

8: Photo Collage Wallpaper

Use family photos to make a customized wallpaper design. Here, Cortney and Bob Novogratz of Home by Novogratz covered one wall of this international models' apartment with the models' headshots for a dramatic yet personal touch.

9: Cork Board

Don't forget about the staircase wall. If you're living in a small space, you can make a workspace underneath the stairs by installing a floating desk against the staircase wall. Designer Brian Patrick Flynn installed corkboard to the wall for a convenient spot to attach memos, cards and photos.

10: Inspiration Quotes

You can find a plethora of inspirational signage in stores, but you can make your own, too. Michelle suggests using different colors and patterns of washi tape for a funky way to display your favorite quote.

14: String Art

If you want to add some retro-style to your home, go with the iconic '70s art favorite — string art. Give it a modern spin with a monogrammed design. Watch the how-to video>>

18: Empty Frames

If you already have a playful accent wall — but want to jazz it up — hang bold empty frames at varying heights. Design by Brian Patrick Flynn

19: Vintage Art Gallery

The metallic floral wallpaper is its own statement piece, but a collection of vintage art really gives this living room a vintage glam look. Design by Emily Henderson

20: Vintage Signs

You can find vintage lettering and signs at just about any thrift store. Cortney and Bob dress up one wall in the dining room with large vintage letters that spell "LUNCH". Paired with animal head decals and diagonal stripes, the letters bring a fun vibe to the space.

21: Wide Stripes

Painting stripes on an accent wall is a fast, easy and inexpensive way to add some color and interest to a wall. Design by Brian Patrick Flynn

22: Thrift Store Art

Thrift stores have one of the best varieties of artwork. Stick to a theme, like animal print or botanicals. Once you have a theme, scour your favorite thrift shops for eclectic art prints that match your theme. Design by Jeanine Hays

23: Jewelry Tree

Living in an apartment or dorm room can prevent you from painting the walls. If you'd like to dress up the walls without damaging them, use washi tape. Michelle Edgemont attached tape to the wall in a tree shape, and pinned thumbtacks to the ends of each branch for a cute, space-saving way to display necklaces.
